The carbonates are compounds of one or more metallic elements or semi-metals with the carbonate (CO32-) radical. One member of this class, calcium carbonate (CaCO3), is sufficiently common to form large bodies of limestone, a sedimentary rock. The carbonates are brittle minerals, and many of them break easily along crystal directions to develop the characteristic rhombohedral cleavage. A few carbonate minerals are in bright colors, but many of them are white, colorless, or transparent. Chesterman, p. 431
